Product Details

The Attwood Marine 66551-3 is a premium thru-hull fitting designed for reliable water system connections in marine applications. Cast from corrosion-resistant 316 stainless steel, this fitting provides exceptional durability in harsh saltwater environments.

Key Features:

  • 316 stainless steel construction for maximum corrosion resistance
  • 1-1/2 inch diameter for standard marine hose connections
  • Integrated sealant channel under flange for watertight installation
  • Wrench flats or end notch for easy installation and removal
  • Designed for above-waterline installation only

This thru-hull fitting is ideal for livewell systems, washdown pumps, bilge pump discharges, and other marine plumbing applications where water lines pass through the hull. The built-in channel under the flange holds a bead of marine sealant to ensure a secure, leak-proof connection. The wrench flats provide positive grip during installation without damaging the fitting.

Important: This fitting must be installed above the waterline only. Not suitable for below-waterline applications.
